I needed a means to obtain the character level and CPs, and I rummaged about in the esoui.com wiki and found this:

GetLevelOrChampionPointsString(level, championPoints, iconSize)

That is the limit of the documentation about it. When I tried to use it, however, the result wasn't what I'd hoped.

Does anyone have more complete documentation about that API function, or know that it doesn't do what I hoped and there is a different one(s) that I should be using? Could it be a data typing issue? I know nothing of how data is typed in LUA or whether it's auto-type-converted as needed.

Other games you just stop gaining XP/levels once you hit cap. So when the cap increases every 3 months, we just get to utilize more of our earned level without additional effort. The downsides being that every update they reduce the XP curve making it easier and easier to level AND when you're above cap, they tack on an additional increase to the curve, which means anything earned past cap prior to an update is vastly slower than post-update.
